| 摘 要： | 研究了液淬工艺参数和添加微量稀土元素Ｃｅ对非昌态Ｆｅ－Ｂ－Ｓｉ合金热稳定性的影响，结果表明，制备非晶条带时的液淬速率愈高，在低温退火时合金的结构弛豫过程愈难进行。而非晶晶化与液淬条件之间不存在直接的联系。Ｃｅ的适量添加，在氏温阶延迟了结构弛豫过程中非晶条带延－脆转变的发生；在高温阶段使合金开始晶化的温度降低，且民条带中Ｃｅ的含量成正比。

| Abstract: | The influences of melt spun parameters and dricro-addition of cerium on thermal stability of amorphous Fe-B-Si alloys have been studied. The higher cooling speed foras-quenched amorphous ribbon, the more difficult for structural relaxation in low-temperatureannealing process. Experimental results show no direct relationship between the quenching condition and crystallization for Fe80B11.5Si8.5 metallic glass. Optimal addition of cerium obviouslyretard the ductile-to-brittle transition process in structural relaxation stage, when annealingtemperature is low. At high temperature annealing stage, the addition of cerium lowers the onsettemperature of crystallization; and this effect is in direct proportion to the content of cerium inribbons. |
